Embodiment Construction
[0025] In order to make the above objectives, features, and advantages of the present invention easier to understand, the following describes the embodiments of the present invention in further detail in conjunction with specific implementations.
[0026] Hole arrangement parameters: Toward the tunneling direction, grouting is performed once every 3-5 shield segments. The hole arrangement parameters can be adjusted according to requirements.
[0027] (1) Buried grouting pipes at the selected grouting holes;
[0028] (2) Determine the ratio of the vibration isolation and noise reduction material resin to the catalyst, that is, simultaneously satisfy the volume ratio of 1:1 and the weight ratio of 1:1.17.
[0029] (4) Connect the injection gun and the grouting pump with a high-pressure hose, use a small multifunctional pneumatic grouting pump, and use a two-fluid grouting system to inject the prepared vibration isolation and noise reduction material resin and catalyst into the grouting h...
